API: Improve glue mid-layer of the API demo application.
- Extend ub_dev_read() and ub_dev_recv() so they return the length actually read, which allows for better control and error handling (this introduces additional error code API_ESYSC returned by the glue mid-layer). - Clean up definitions naming and usage. - Other minor cosmetics. Note these changes do not touch the API proper, so the interface between U-Boot and standalone applications remains unchanged. Signed-off-by: Rafal Jaworowski <raj@semihalf.com>
